Radial Engineering Ltd. in Vancouver, British Columbia, announces a revised version of its EXTC 500 Series module ($300 MSRP). The EXTC converts a balanced signal to a guitar level effects loop, and then re-converts it back to a balanced level for processing. This allows the engineer to incorporate an unlimited range of guitar effects into a production using one device.
Designed to fit inside both traditional API style 500 Series Lunchbox frames and the Radial Workhorse, the EXTC begins with a frame mounted XLR input connector, where it receives the line level signal from the recording system. The signal is then unbalanced and converted to high impedance where guitar effects pedals can be inserted as desired using front mounted ¼-inch jacks. The latest version features a transformer-coupled output to eliminate potential ground loops from causing hum in the recording system.
Individual front panel send and receive controls allow precise signal management, which is augmented with a mix/blend function that allows the original tone to be mixed in for the desired wet-dry balance. Because guitar pedals can often reverse the signal phase, the EXTC incorporates a 180-degree polarity reverse that flips the input polarity of the pedal chain at the receiving jack so that the wet and dry signals work together and play in-phase. Once processed, a gain make-up buffer provides the engineer with a solid signal to feed the recorder using the balanced XLR output or via the Workhorse master section. Both XLR and ¼-inch TRS connectors are supported.
When used with the Workhorse, the Omniport is designated as a TRS send and receive to allow the EXTC to be normaled to a standard patchbay. This allows both standard studio effects and guitar effects to be combined. The EXTC now offers a bus driver that feeds the Workhorse mixer, which allows multiple signal paths to be used at once.
